What does the customer see when they have been banned from the store? Do they still see the store but cant login or do they just get a blank page?

Thank you for raising this again sergaerg.
Did you ever get an answer to this ansuk?

They get an error message that says:
 
"This action is not allowed from your host"
 
Of course you can change the message from the admin center via static messages

Thanks, Dan - hopefully the new manual will cover details like this in depth ... and be easily searchable
